CRITICAL: Crashing on API Update with 5.5.1p1

[evanlewis]

Hello,

I am working on upgrading our Unity engine to version 5.5.1p1 and am experiencing a problem when updating the NodeCanvas API to 2.6.2.

Every time I try to update the API (via the menu, or via the button on the FSMOwner gameobject), Unity crashes. This is my system dump from the crash, it’s the same every time. Not sure what to make of it, but it seems like something is going wrong with a serialization step. Please advise! We use NodeCanvas for just about everything in our game 🙂

Hello,

First of all, I am sorry that this is happening to you. That is the first time I’ve been reported this issue though. The dump log looks quite cryptic as well.

Just so that we rule some possible causes out, is it possible for you to run the Project Updater process while still in Unity 5.4 (or any other prior version) and let me know if the crash (or any other issue) still occurs?

Another thing to please try would be to set the Project Settings/Editor -> Asset Serialization Mode to “Force Text”, close and re-open Unity before running the Updater process. (This is mostly an assumption though, since it looks like the crash occurs after this line “IsObjectNonTextSerialized” in the dump log)

Please let me know on the above.
Thanks in advance!

This is the exact same issue I’m having (see my forum post on this matter here. Was this ever figured out? Tons of FlowCanvas and NodeCanvas use in our entire project, and can’t do anything beyond this. Thanks much!
